My invention relates to improvements in a combination stop action fororgans.

One of the objects of this invention is to provide an efiicient andeconomical combination stop action for a pipe organ, especially adaptedfor a direct electric organ, whereby the organist can conveniently andspeedily set-up, and likewise repeatedly and alternately bring intoservice, various stopkey combinations, from the organ bench and whileplaying the organ.

A more particular object of this invention is to provide a mechanism forsetting-up organ stopkeys in combination, which comprises improvedsetter means provided with lock means arranged to eliminate frictionbetween movable parts, preferably by the use of a lock member havingflexible or hingedly mounted locking elements thereon, whereby areduction is effected in the amount of electrical current required foroperating the same.

These and various other objects and advantages are attained with thisinvention, as will become apparent from the following description, takenin connection with the accompanying drawings wherein my invention isshown. in its preferred form, it being understood that various otherarrangements and forms of construction may be adopted for carrying outthe objects and purposes of this invention.

This invention briefly pertains to the type of pipe organ provided withseveral combination pistons, by each of which the organist is enabled tooperate a certain group or number of stopkeys simultaneously, withoutoperating each one individually. The master piston is associated withseveral combination pistons, and it is depressed when the stopkeysdesired in a selected combination have been drawn or moved into the onposition, and the combination piston is then also pressed whereon saidstopkeys are being setup. After thus setting-up the desired stopkeys onthe particular combination piston, the two pistons are released, and thedrawn stopkeys are returned to their released or off position.

Thereafter, every time this combination piston is pressed, thecombination of stopkeys set-up thereon is automatically operated.

My invention is an improvement over such combination stop actions, andin the drawings, by way of example, two stopkeys H and H are shown,being illustrated in connection with one of the combination pistons l2and the means whereby said stopkeys are set-up on this piston, to beoperated thereby.

Other combination pistons as indicated at l2a, are similarly arrangedand adapted to have a group of stopkeys set-up thereon.

The stopkeys I I and l l are provided with actuating units l4 and I4,substantially as indicated in Fig. 1 of the drawings. Each of said unitsincludes an off magnet I5 and an on magnet l6 mounted on magnet bar 11.An armature bar I8 is pivotally mounted on bar l'l, extends between saidmagnets, and carries on its outer end a pair of oppositely extendingcurved arms l9 and 20, adapted to be attracted by cores 2| and 22 ofsaid magnets l5 and I6, respectively. A rod 23 is pivotally connected toa finger 24 on said armature and to an arm 23 on the stopkey, adapted tomove the stopkey to the on or the off position.

These parts are shown in the off position or position of rest in Fig. 1of the drawings; and the stopkey and armature are also indicated bydotted lines in the on position. The stopkey actuating unit [4 compriseselements like those of the unit l4, being denoted by the same numberswith the prime mark added thereto.

When the stopkey H is drawn or moved from the full line position to thedotted line position of Fig. 1, arm 25 and rod 23 move finger 24, whichin turn brings the movable switch contact 21 into engagement with thestationary switch contacts 28 and 29 of this switch unit. Said contact28 of this switch, and similarly contact 28 of the a switch for stopkeyH, are connected with the organ stop circuits 3D and 30, respectively,as indicated in said Fig. 1.

A setter switch unit is provided which is active in setting-up acombination of stopkeys on the piston l2. The unit comprises a magnet 3|which is supported and grounded with its core 32 on a metal bracket 33,and an armature bar 34 extends from the bracket, having a curved arm 35adapted to be attracted by and movable across said core 32. nected toarmature bar 34 and carries movable contacts 5?, 38, 3S, and 39 thereon,cooperating respectively with stationary contacts 41, 42, 43, and G3.The movable contacts 39 and 39 are connected respectively by wires 44,and M with the stationary contacts 29 and 29' of the stopkey actuatingunits i and I4; and the switch contacts El and 42 are connected by wires45 and 46 with the stationary contacts 41 and 48 of the combinationswitch of piston l2, said contacts being engaged by a movable contact49, and the switch closed upon pressing the piston.

Combination piston l2a is similarly provided with stationary switchcontacts 41a and 48a and with a movable contact 49a for closing theswitch, and is similarly equipped and connected with a plurality of stopkeys adapted to be set-up thereon, as will be understood withoutduplicating the illustration.

A master piston or toe piston 50 is provided, which is depressed toengage its movable contact 5! with its stationary contact 52. A wire 53extends from contact 5! to a source of power 54, for example, agenerator, from which a wire 55 leads to the bracket 33 of magnet 31,and a wire 56 with a branch 56' connects said wire 55 with magnet barsI? and ll, respectively; while a wire 5'! extends from wire 53 tocontact Zl, having a branch 5'. extending to contact 27. A wire 58 leadsfrom contact 52 to the coil winding of said magnet 35. By depressing thetoe piston 55 the circuit thru the magnet 3| is completed, currentflowing from source of power 54 thru wire 53, contacts 5| and 52, wire59, magnet 31, bracket 33, and thru wire 55 back to the source of power54, thereby energizing this magnet to throw these setter switches.

A combination setting and retaining mechanism is furthermore provided,which cooperates with the setter switch unit and is brought into servicein setting-up and retaining the stopkeys combined on the piston. Thisincludes a combination switch 5! a switch moving unit SI, and a switchlocking unit 62. There is such acombination switch 58 and a switchmoving unit 6| provided for each stopkey; while a locking unit 62 isprovided for each combination piston 52, and it includes a group oflocking elements for cooperation with a group of combination switches,each element cooperating with a combination switch to retain it set.

As best shown in Fig. 3, the combination switch 68 includes an offcontact 63 and an on contact 84, also a charge contact 65 extendingbetween the two, and adapted to be brought into engagement with eitherone thereof. The off contact 63 is connected by a wire 61 with the offmagnet l5, and the on contact 64 is connected by a wire 68 with the onmagnet l6. Said switch is mounted with suitable insulation on a bar 69supported on a main frame or frame means 10.

The contact moving unit 6| includes a trace bar i5 having a slot 12,thru which extends a screw '53 arising from a supporting bar 14 which Amain bar 39 is pivotally conis supported on frame means it. Said tracebar has openings '15 and 15a, wherethru extend the contacts 65 and 65aof combination switches 68 and Gila, to be moved forwardly andrearwardly into the on and the off positions. A trace bar magnet 16 ismounted by its core TI on a bracket 78 which is adjustably mounted by aslot and screw means 80 on a metal cross-bar 8!. (See Fig. 4.) Anarmature 32 is pivoted on bracket l8 and its bent end 83 is attracted bymagnet core ll, while a rod 84 on the armature is connected to trace barii to move it and the several switch contacts 65, 85a, forwardly fromthe off position, as shown in Figs. 1 to 5, to the on position as shownin Figs. 6 and '7. A spring 85 is connected to bracket 18 and toarmature 82, adapted to return the latter and the trace bar to the offposition.

As best shown in Figs. 2 and 3, there are several switch contacts, 65,65a, in a row, which are moved by said trace bar ii of unit 6!, each oneof said contacts and the associated stopkeys being adapted to be set-upon different combination pistons, l2, l2a, etc., so as to be inclusivewith stop-keys H and contacts 65 of other rows, in several dififerentcombinations.

The switch locking unit 62 includes a lockbar 87 which extends acrossthe several switch moving units 6!, SI, as best shown in Fig. 2 anddiagrammatically indicated in Fig. 1. Said. bar has a plurality ofnotches 88, 88, etc. provided therein, and across the front of each ofsaid notches is mounted a flexible lockbar plate, 89, 89', etc., eachplate being swingably mounted on the bar, preferably by a pair of pins98 secured on the bar and extending thru enlarged openings provided inthe plate, whereby the plate is hingedly or swingably mounted on thebar, forwardly o the opening, and is adapted to yield when a s-.-. acontact 65 is drawn forwardly thru the notch 83 toward its lockingposition. The i mounted on a shaft 9! being positioned forwardlythereof, and said shaft is rotatably supported on brackets 92 which areadjustably mounted on frame means 10, by slot and screw means 92, forexample, as indicated in Fig. 2.

This flexible and swingable arrangement of the locking plates enableseach one of the plates 89, 8%, etc., in a row to yield readily when thetrace bar H is drawn forwardly by magnet l5 pulling the row of contacts65, 65a, etc., against said plates, while moving into the on position.The particular plate 89, by operation of its lockbar Bl, can then bereadily drawn upward or raised above the particular switch contact 65 ofthe selected combination, as indicated in Fig. '1, without creating anyappreciable friction, to be thereafter dropped back of said contact, asshown in Fig. 6.

This locking unit 52 is operated by a lock bar magnet 93 which ismounted with its core 94 on a bracket 95 secured on a bar 96 supportedon frame means 10, while the armature bar 9"! is pivoted on the bracket95 and has a bent end 98 movable across the magnet core A rod 99 ispivotally connected to the armature bar and to an arm I06 arising fromthe shaft 9|, whereby said shaft is rotate when the magnet is energized.A spring I96 is connected to said armature bar 91 and to a plate 162which is adjust-ably mounted by slot and screw means U33 upon bar 96 onframe means 70, thus providing for adjusting the tension of the spring.The lockbar 8'! is thereby automatically returned to its off positionwhen magnet 93 is de-energized, and a stop bracket N14 with suitablecushioning means limits Cir K said contacts.

the movement of armature bar 91 to the off position.

It should be noted that in this illustrated construction theelectromagnets have their negative lines connected to the steel frame ofthe mechanism, since the coil winding of each magnet is grounded on thecore, and the core is mounted on the steel frame. This arrangementrequires only one wire extending from each coil, as indicated in thedrawings, and it eliminates the necessity of running a second wire toeach coil.

The trace bar moving magnet '16 has its coil winding connected by a wireI05 to contact 43 of the setter switch unit; and magnet I6 is similarlyconnected by a Wire I05 with the switch contact 43'. A wire I55 connectsthe metal cross 8| electrically with wire 55 which leads to the sourceof power 54.

The locking unit 62 has its magnet supporting bracket 95 connected by awire ID'I with wire 55 leading to source of power 54. The coil windingof magnet 93 is connected by a wire I08 with contact 38 of the setterswitch unit.

The other contact moving units GI are like unit 6|, comprising similarmembers correspondingly numbered, each unit including the magnet '45 onbracket 18 grounded on said metal cross bar BI, like bracket 16; alsoincluding the trace bar II moved by armature 82, as best shown in Figs.1 and 2.

The other combination switches 60 are like switch 50, each comprisingcontacts 63 and 64, and the movable contact 65 positioned therebetweenand movable by its trace bar 1!. Wires 61 and 68' connect said contacts63 and 64, respectively, with magnet I5 and I6 of the actuating means ofstopkey II.

A combination operating unit H6 is provided which is brought intoservice when the combination piston i2 is depressed for operating thestop combination on said piston. This operating unit includes anoperating magnet III provided with a core I i2 whereby it is mounted ona bracket H3 which is secured on the metal cross bar BI. An armature H4for said magnet is pivoted on the bracket and its bent end H5 isattracted by the magnet core II2.

These operating magnets I I I are mounted with their brackets M3 onmetal cross bar 8|, below the trace bar moving magnets I6 with theirbrackets 1'8, both sets of magnets being grounded on said bar,substantially as indicated in the drawings.

As best shown in Figs. 5 and 6, this unit III] also includes a roller H6which is swingably mounted in brackets IIl supported by frame means I0,and it has a metal contact strip II 8 extending longitudinally thereofand projecting from its periphery, adapted to establish contact with theseveral movable charge contacts 65, 65, when the roller is swung. A rodH9 is pivotally connected to an arm I on roller H6 and to an arm I2I onarmature I I4, for swinging the roller to establish the contact betweensaid strip and A spring I22 is connected to bracket and to armature Iil, for returning the latter to the off position. A contact blade I23 issupported by means I24 on frame means In and is adapted to make contactwith said metal strip H8, and a wire I25 leads from said blade to thewire 53 which is connected to the contact 5| oi the toe piston; while awire I26 extends from the coil winding of magnet III to the contact 4!of the setter switch unit.

Further mechanisms are provided, of course,

for setting-up and bringing into service different groups of stopkeycombinations on other combination pistons, which are operativelyconnected with the master piston. This is indicated in the drawings, bypiston I2a with its switch contacts 41a, 48a, and 4 911, the latterbeing shown connected with the wire 53 extending from the master switch.It is further indicated by the combination switch 65a with its contact63a, 64a, and 65a; also by the trace bar locking unit 62a with itslockbar 81a, shaft 9Ia, magnet 93a, and rod 99a connecting the armature91a with arm IOIla on said shaft am, the roller H60, and its contactstrip II8a being adapted to engage contacts 55a, the same as disclosedabove.

The operation. of the disclosed mechanism is as follows The variouselements and parts of the mechanism are normally in the off position orposition of rest, as indicated in Figs. 1 to 5 of the drawings, but someof the stopkeys may be in their drawn or depressed position.

In order to place all depressed stopkeys associated with the combinationpiston I2 into the off position, the piston is pressed making contactbetween elements 49 and 41, whereupon the current passes from source 54through wire 53, contacts 49 and ti, wire 45, contacts 31 and M, wireI26, magnet III, bracket II3, metal bar 8I, wire I06, and wire 55 backto the source 54, there by energizes said magnet and swinging strip H8into engagement with contact 65; whereupon the current flows from thesource 54 to wire 53, wire I25, contact element I23, strip II8, contact55 and63, wire 61, magnet I5, bracket i1, wire 56, and thru wire 55 backto source 54. The energized magnet I5 thereby draws its armature I9 andstopkeys II into the released or off position.

The combination of stopkeys can then be set-up on the piston. Thisoperation involves the following steps:

First.Draw or press down the particular stopkeys which are desired to beincluded in the combination on the piston I2. This brings the stopkeysin the on position and draws the armature from magnet l5 to magnet l6,thereby engaging contact 2! with 28 and 2S.

Sccond.Depress the master piston or too piston and hold it depressed.This engages switch contact 5I with 52, closes the circuit thru wire 53,magnet 3!, bracket 35, wire 55, source of power 54, wire 53, and thrusaid contacts, thereby energizing magnet 5i and moving switch barseparating contact 31 from 4|, and engaging switch contact 38 with 42,39 with 43, and 39 with 43'. This completes the trace bar magnetcircuit, from source 54 thru wire 53, wire 51, contacts 2? and 25, wire44, contacts 39 and 43, wire I65, magnet 76, bracket 18, metal bar BI,wire I06, and thru wire 55 back to source 54. The switch 31, 4| beingopen, the circuit thru the combination operating magnet I I i will bebroken, thus rendering said magnet inoperative during the setting-upoperation.

The energized magnet l5 actuates its armature 82 and draws trace bar Iiforward thereby drawing the associated contacts 65, a forwardly thru thenotches 88, 88a, against the lockbar plates 88, 89a, and as said platesare flexible and swingable they will yield to enable such movements ofthese contacts. The contact 35, which is to be included in thiscombination, is thereby moved against the companion contact 64, to closethe circuit thru this combination switch to its on magnet 16.

Third-Press the combination piston l2. This engages switch contact 9with contacts 41 and it, and current flows from source 54 thru wire 53,contacts t5 and 48, wire it, contacts 42 and 38, wire E88, magnetbracket 95, wire I01, and thru wire 55 back to the source 54; therebyenergizirr magnet and drawing its armature S? and the rod 529 to wingshaft 95 and raise the lockbar 8i and therewith the lock plates 89. Thisenables the raised lock plates 89, which have been fi forwardly by theforwardly drawn contacts that are associated with the depressedstopkeys, to pass over said contacts to the rear thereof.

Fourth.Rele-ase the combination piston I2, thereby breaking the circuitthru the locking magnets whereupon the lockbar 8'! with its lock plates83 drops back of the selected contacts to retain them in the onposition, as indicated in Fig. 6.

Fifih. Release the toe piston or master piston thereby separating switchcontacts 5! and and breaking the circuit thru magnet 3i, whereuponswitch bar 36 moves to its initial position, thereby again connectingswitch contacts 3i and again separating switch contact from 39 from and35' from 43'. This again completes the broken path betwee the source ofpower 55 and the operating magnet.

Sixtir.Upon presssing combination piston l2, for bringing into servicethe stopkey combination set-up thereon, the current passes from sourceof power 5 thru wire contacts 39 and wire 5 contacts and wire magnet Hi,bracket H3, bar 85, wire i533, and thru wire 55 back to the source ofpower 54; thereby energizing magnet Hi and operating its armature i andthe connected rod iii), to swing roller and make contact between itsstrip H8 and the locked contacts etc., as well as with contact member iThis closes the circuit from source of power thru wire 53, wire i252,contact member E23, strip H8, contacts 55 and wire on magnet i8, magnetbar b0. i'?, wire 53, and thru wire 55 back to the source of powerthereby swinging the armature to the on magnet 55 and moving the stopkeyinto its depressed or on position. The depressing of the combinationpiston thus brings all the stopkeys that a set-up in combination on thispisteinto the des ed service position.

To iree the stopizeys from the combination in which they have L set-up,proceed as follows: First.-Place s a stopkeys in their raised or releaseposition, in Fig. l.
